T 0 all whom t may concer-n;

Be it known that NORA LEAH KENNER, a

residingat Cordell, in the county of Washita and State of Oklahoma, has invented -new and useful Improvementsin Dishwashers,

fof which the followingis a specification.

The object of the invention is to provide a simple and' eicient means whereby -dishes and like breakable articles may be cleansed mechanically or without mahual contact or lmanipulation under conditions'resulting in thorough sterilization without the risk of fracture', and -may then be withdrawn from 'the washingor rinsing Water'and drained carrier.

The apparatus consists essentially of a stationary receptacle or vessel 10 which as illustrated may be supported upon a suitable framework consisting of the legs 11 and braces 12 inwhich iszmounted a rotary carrier or cage 13 designed-to receive the dishes or artic es to be cleansed and provided with suitable racks or bars 14 for facilitating the Vstacking and holding of the articles in proper positions to aiford access vof the water or cleanslng liquid to the surfaces thereof,

f ment upon a spindle. 16 disposed axially in said carrier or cage being provided with a` tubular shaft 15 mounted for sliding movethe receptacle or vessel 10, in connection with l operating means 17 for communicating rotary motion to the carrier and lifting means 18for removing' the carrier or' cage' from vthe receptacle or vessel to permit of thev draining and drying of the'contents thereof. In. the illustrated embodiment of the im vention the tubular shaft 15 of the carrier or cage (adapted to 'be covered when positioned in the vessel or receptacle 10` by means of a cover 19 fitted on the latter and having an inverted conical upper surface to afford drainao'e toward the central opening 20 through which the said shaft extends), is providedy wlth a bevel pinion 21 withwhich dette meshes aV bevel gear22 having a.. shaft 23, which is mounted in a bearing in a sleeve 24 lwhich receivesthe upper end of the tubular shaft 15, and which. extends into a slot 25 formed in a standard 26 which rises at one A side of the receptacle or vessel with a bearing 27 at the lower end thereof to support the shaft when in operative position or when the shaft is being turned-to impart rotary motion to the carrier. operating crank arm 28 is provided with aj sleeve 29 fitted on the gear wheelspindle 23;'and having a clutch connection with the'shaft by means of notches 30 therein arranged forengagement' with radial pins 31 on thefshaft. 1- By. means of the sleeve it is obvious that the crank may be moved out of operative connection with the shaft by disengaging the members of the clutch to permit of independent rotation of thecarrier.

When the parts are inthe washing posi'- tion indicatedin Figure 1 in full lines with theshaft of the driving gear 22 in the bearing at the lower, end of the slot in the standard 26 it may be Vlocked in place b means of-a latch 32, so that vibration of the shaft incidental to the rotary motion thereof may be prevented. When it is desired to raise the carrierI with its contents ont of the liquid contents of the receptacle or vessel 10 the latch may be disengaged from said driveJ shaft, and t ereupona lever 33 forming a part of the lifting mechanism and which is pivot'ed as at 311 upon the upper end of the standard 26 may be moved from the full v position indicated in Figure 1 to the line position therein, said lever being connected by a' suitable linkV 35 with the,

line

sleeve The elevation ofthe sleeve carries with it the `tubular shaft which supports A the carrier, and'also carries with it the drive shaft to occupy.l the elevated position indicated in dotted lines in Figure 1. The lid or cover 19 of the receptacleor vessel 10 1n for the tubular shaft of the carrier is radially slottedas indicated at 20a to permit o f application and removal thereof, and obviously when it is desired to raise the car- 'addition to having thev central opening 20 los rier for the purpose of draining the cont-ents th eof the cover should first be removed, and after the lifting lever hasbeen actuated as herein-above indicated the cover may be replaced to 'serve as a supper-tv for the carrier, and as said cover is inchned toward its centerto form a drainage surface and-the,

L y ,A

Walls and bottom of the carrier are perfo-Y carrier when thus supported in an elevated position and will pass back into the vessel and leave the dishes in a dry condition provided of course the water from which th'ey have been Withdrawn is of a sufficiently high temperature. Or after the carrier has been raised to thedraining position subsequent to the washing operation which is conducted by a more or less rapid rotation of the carrier in the liquid contents of the receptacle, boil ing or other hot rinsing Water may be poured over the dishes in the carrier and permitted 'to drain back into the vessel or receptacle.

Having described the invention, what is claimed as new and useful is:-

1. A dish washing apparatus having a' vessel or receptacle for cleansing liquid, f1 rotary ca rrier or cage mounted in the vessel or receptacle for axial movement tol a position above the liquid contents thereof, operating mechanism foiimparting rotary motion to the carrier or cage, and liftingl `mechanism for raising the carrier orcage to its elevated position, the carrier or cage having an axial shaftand means for supporting the same (for axial movement, and a sleeve embracing the upper end of said shaft,

and said operating,r mechanism having a drive shaft geared to the carrier shaft anrl mounted at its inner end in Aa bearing in said sleeve, the said drive shaft being mounted at its outer end in a slotted standard, and means being provided for holding said shaft against displacement when the carrier is in its operative position.

2. A dish washing apparatus havingT a vessel or receptacle for cleansing liquid, a

rotary carrier or cage mounted in the vessel or reception for axial movement to a position above the liquid contents thereof, operating mechanism for-imparting rotary motion to the carrier or cage, and lifting mechanism for raising the carrier or cage to its elevated position, the carrier having a shaft, and a sleeve having a swivel connection with the. shaft, and the lifting mechanism having a lever Aoperatively connected with said sleeve. y

Y In testimony whereof she aiixes her signature. Y
